maximum time the device takes to acquire the signal.
Calculate this with the following equation:
t
ACQ
= 7 (R
S
+ R
IN
) C
IN
where R
S
is the source impedance of the input signal,
R
IN
is the T/H input impedance (40k&), and C
IN
is the
input sampling capacitance of the ADC (4pF). Source
impedances below 100k& have no significant effect on
MAX1298/MAX1299 AC performance.
Analog Input Protection
Internal protection diodes clamp the analog inputs to
V
DD
and GND, so channels can swing within GND -
0.3V and V
DD
+ 0.3V without damage. However, for
accurate conversions, the inputs should not extend
beyond the supply rails.
If an off-channel analog input extends beyond the
supply rails, limit the input current to 2mA.
Serial Digital Interface
The MAX1298/MAX1299 feature a serial interface that is
fully compatible with SPI, QSPI, and MICROWIRE
devices. For SPI/QSPI, ensure that the CPU serial inter-
face runs in master mode so it generates the serial
clock signal. Select a 2.5MHz clock frequency or less,
and set zero values for clock polarity (CPOL) and
phase (CPHA) in the 礟 control registers. Figure 4
shows detailed serial interface timing information. See
Tables 25 for programming information.
